useful Improvements in Line-Composing Machines, of which the followingis a specliication.

This invention relates to improvements in line composing and typecasting machines and more especially to those of the. well knownlinotype class, and it is the object of the invention to provide animproved connection between the line delivery carriage or slide'and itspower-operated means whereby the line delivery carriage will bedisconnected more readily and with greater certainty should the movementof the carriage become obstructed or the operation thereof interferedwith in any way to impede or prevent its return to normal position.

The line delivery carriage serves to convey the line of matrices fromthe assembling elevator to the first elevator prior to presentation ofthe line casting `mold, and the present invention avoids damage eitherto the matrices or to other working parts of the machine in-emergencies,such as those referred to above.

Fig. 2 1s a pering the present invention; spective view of the operatingline delivery carriage constructed in accordance with the presentinvention.

. Similar parts are designated bythe same reference characters in theseveral views.

The accompanying drawing shows the invention applied to line deliverymechanism of the type employed generally on machines of the linotypeclass, but it will be understood that the invention is not restrictednecessarily to the particular construction shown, as equivalentstructures may be used and they will be included within the terms of theclaims at the end .of this specification. In the present instance, 1represents the lever or arm which serves to reciprocate the linedelivery carriage, this lever being iiXed to a rock shaft 2. A spring 3operates to swing the lever or arm 1 to the left, while a cam is usuallyemployed to rotate the shaft 2 to swing the lever or arm 1 positively tothe right and' against the action of the of matrices to the lineoperating means,

link for the extends through spring. The line delivery carriage isguided to reciprocate on the frame 4 of the machine and the linedelivery carriage is composed usually of slidable blocks 5, 6, 7 and 8,a pair of downwardly projecting fingers 9 and 10 serving to receive eachline of matrices between them and to convey the liney of matrices fromthe assembling elevator to the rst elevator in a manner well known tothose skilled in the art. The

blocks forming part of the line delivery carriage are connected by alongitudinal bar 11 whereby the elements of the carriage willreciprocatev in unison.

Obviously, the construction of the line delivery carriage is notessential to the present invention and hence may be varied, that showncorresponding to the construction commonly employed. Experience hasshown .that the return movement of the line delivery carriage is apt tobecome obstructed or retarded from certain causes, such, for example, aswhere the line of matrices has not been proper y removed, and the objectof the present invention is to provide means whereby the line carriagewill'become disconnected automatically from its operating means, therebypreventing damage to the matrices, the carriage, or other parts of themachine which would otherwise result owing to the positive movement ofthe carriage and leaving the carriage in a position which will enablethe operator to relieve the congestion.

The automatic, disconnecting means may, according to the presentinvention, be constructed in different ways. In the present instance, itis embodied in the link which normally forms an operative connectionbetween the line delivery carriage and its actuating lever or arm 1. Thelink 19. rin the construction shown is provided at one end with a notch13 to receive a pin 14 which latter is fixed to the line delivesycarriage, and the link is provided with a pair of bearings or guides 15and 16. A rod or bolt 17 and is capable of longitudinal movement in thebearings 15 and 16, and this bolt is provided atone end with a head 18which has a pin 19 xed thereto, this pin having a pivotal engagementwith the actuating lever or arm 1. The opposite end of the bolt or rod17 is movable to and from a position across the opening presented by thenotch 13, the no h `in the present con- "link relatively to the isprovided which struction presenting its opening toward the bottom of thelink and when the end of the bolt 17 projects across the opening of thenotch, it will lock -or retain the pin 14 therein and thus preventdisconnection of the carriage. Preferably, the upper side of the bolt 17opposite to the notch 13 is` flattened to .afford a suitable bearing forthe lower side of the pin 14. The wall 2O of the notch 13, which wallserves to transmit motion from the link to the line carriage in adirection to return the carriage to normal position, is beveled orinclined, as shown. A spring is employed which serves normally to retainthe bolt 17 in a position to lock the pin 14 in the notch 13. In thepresent instance, a coil spring 21 encircles the bolt 17, one end ofthis spring abutting against the bearing or guide 16 on the link and theother end of the spring abutting against a collar or shoulder 22 whichlatter is fixed tothe bolt and is normally held by the spring againstthe bearing or guide 15 of the link. The link, therefore, provides apositive connection between the line delivery carriage and its actuatinglever or arm 1 when the latter is driving the carriage forward or to theleft under the influence of the spring 3,'but during the return movementof the line delivery carriage by positive operation of the actuatinglever or arm 1, the power is transmitted from the actuating lever to theline delivery carriage through the medium of the spring 21. Therefore,should the return movement of the line delivery carriage be retarded orchecked from any cause, the continued movement of the actuatinP lever 1will cause retraction of the bolt 1 this being permittedl y compressionof the spring 21. The tension exerted by the link on the line deliverycarriage will tend to disengage the link from the pin 14 owing to theengagement of the pin with the beveled or inclined surface 20 of thenotch, and when the bolt 17 has been retracted to a predetermineddegree, its end opposite to the notch 13 in the link will have becomeretractedV to a degree suiicient to permit escape of the pin 14 from thenotch,

and the link will then be disconnected from the carriage and thecarriage may remain stationary while the actuating lever 1 completes itsmovement.

he present invention provides an improved connecting device whichautomatically disconnects the line delivery carriage from its operatingmeans when the tension on` the carriage reaches a predetermined point,owing to the fact that the bolt 17 must be retracted to a predeterminedextent before the parts are disconnectcd,'and in the presentconstruction, the tension required to disconnect the parts is notad'ected by the angle `of the surface 20. It is advantageous to ploy acoil spring to retain the bolt in normal position, as springs of thatform can not only be made easily and cheaply, but it is comparativelyeasy to make all of the springs of the same tension for machines in'use.

It is obvious that the link can be applied in a reverse position to thatshown, that is to say, the notch and its locking bolt may be arranged toengage a pin ony the actuating lever. Other equivalent constructions andarrangements may be used which are included within the scope of theclaims.

claim as my invention 1. In a machine of the lintoype class, thecombination of the line delivery carriage and means for operating thesame, embodying a pin on one of the parts adapted to engage in a notchin the other part, and a bolt to normally lock the pin in said notch andoperative to unlock the pin automatically by a relative movement betweenthe carriage and its operating means.
